We study the impact of timing and commitment on adaptation and mitigation policies in the context of international environmental problems. Adaptation policies present the characteristics of a private good and may require a prior investment, while mitigation policies produce a public good. By developing a stylized model, where some countries coordinate their actions while others do not, we evalu...

There is insufficient knowledge regarding the role of personality traits, transport-related risk cognitions and safety motivation for demand for transport risk mitigation. The aim of this study is to test a model aimed to predict public demand for transport risk mitigation by these psychological risk constructs. A mailed self-completion questionnaire survey was conducted in a random sample of t...

Improving the knowledge about marine mammal ecology and about how ocean dynamics affect their distribution and behavior in different areas; Developing the tools enabling to predict marine mammal presence probability or density on the basis of the data available to detect their presence (i.e. visual observations or acoustic detections) and the available environmental predictors; Creating the kno...

A hidden failure embedded DC model of power transmission systems has been developed to study the power law distributions observed in North American blackout data. We investigate the impacts of several model parameters on the global dynamics and evaluate possible mitigation measures. The main parameters include system loading level, hidden failure probability, spinning reserve capacity and contr...

this paper presents future trends of urban wastes and their impacts on the environment of african cities using plausible mitigation scenarios. to accomplish this, an integrated dynamic model for urban waste flows was developed, tested, calibrated and validated. its parameter sensitivity was analyzed. using population projection up to 2052 with different levels of technological implementation, p...

COVID-19 the existing contagion is caused by SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2). As of 1st March, 2021, statistical study shows, 114 million people all over world have been affected and in this about 2.53 deaths reported with a recovery 64.4 cases. The most commonly testified signs infection are pyrexia, tussis tiredness; other symptoms that less common include depriva...

The aim of this study is to investigate the flood management and mitigation measures in ungauged NATURA protected watersheds. examined watersheds are located one most European significant areas (Prespa Natural Park North Greece). SCS-CN model was applied perform hydrological modeling for extreme rainfalls 50, 100 1000 return periods. Extensive field research conducted record all hydrotechnical ...

Abstract Artificial lift is a vital part of the life many oil wells worldwide. Using several artificial methods can prolong and increase recovery significantly. One most applied nowadays electrical submersible pump (ESP). This method has ability to handle large volumes hydrocarbons applicable under conditions in both offshore onshore reservoirs. Even though ESP been extensively for years, it st...
